Still recovering from his life-threatening wounds, private detective Charlie Parker investigates a case that has its origins in a Nazi concentration camp during World War II, in this 13th thriller of the series by Agatha, Anthony, Barry, Edgar, and Shamus Award–winner John Connolly (following The Wolf in Winter). Parker has retreated to the small Maine town of Boreas to regain his strength, and befriends a widow named Ruth Winter and her young daughter Amanda. But Ruth is keeping secrets, and old atrocities are about to be unearthed. Parker risks his life to defend a woman he barely knows—one who fears him almost as much as she fears those who are coming for her.

"Connolly infuses his thrillers with enough of the supernatural to please fans of both genres, but it's his sense of humor, timeless characters, and impeccable writing that make his work worth reading."—Kirkus Reviews (starred review)
